Rhetoric vs. Reality
Like a lot of protectionist policies in the United States, the U.S. anti-dumping law dates back more than a century and has expanded far beyond its original scope and intent. As Dartmouth’s Doug Irwin explains in his book, Clashing Over Commerce, the original Antidumping Act of 1916 was intended to discipline anti-competitive “predatory pricing”: In particular, it “made it illegal to sell imported goods at prices substantially lower than the market value in the exporting country ‘with the intent of destroying or injuring an industry in the United States.’” However, because proving foreign exporters’ “predatory intent” in U.S. courts was difficult and time-consuming, the law was rarely used. So Congress, naturally, went back to the drawing board a few years later and, in the Antidumping Act of 1921, “changed matters considerably.”
Under this new version, which (along with the Tariff Act of 1930) is the foundation for today’s anti-dumping law, there is no “predatory intent” requirement; AD cases moved from the courts to the bureaucracy; and AD duties simply police price discrimination. Thus, the treasury secretary could impose anti-dumping duties on imports if an investigation determined that 1) they were sold in the United States at less than “fair value” (i.e., the price charged by the exporter in its home market) and 2) were injuring the U.S. industry making the same product. As Irwin notes, “a foreign exporter charging a lower price on its sales in the United States than in its own home market could be found guilty of dumping”—regardless of the exporters’ intent or any other circumstances. The difference between that home market price (say, $110 per widget) and the U.S. export price (say, $100 per widget) is the “dumping margin,” which is then converted to a final AD duty rate applied to subject imports by dividing the margin over the company’s U.S. sales: In our very simple example, (110–100)/100 equalsa 10 percent tariff—on top of any normal tariff the U.S. already applies on the product.
Thus arises the first problem with the anti-dumping law and common allegations of “dumping”: Price discrimination alone is a horrible proxy for any sort of “unfair” or anticompetitive trading practice, including the most common ones today linked to “dumping”—i.e., predatory pricing or closed (“sanctuary”) home markets. As my Cato colleagues have written repeatedly, there are plenty of legitimate, commercial reasons why a company might charge a higher price in its home market than in an export market, and this kind of price discrimination happens every day in the United States—in international or interstate trade—in all sorts of industries. It’s totally normal stuff, yet it’s dutiable under the anti-dumping law.
Subsequent revisions to the law define “dumping” as also occurring when a foreign company sells in the U.S. below its cost of production. This is closer to something that might indicate “unfair” trade (e.g., foreign subsidies or sanctuary markets), but there are still many normal (non-predatory) reasons for why below-cost sales might occur: For example, temporary “loss-leader” sales in an important new market or for a new, untested product; financially weak companies selling off assets to pay creditors instead of declaring bankruptcy; severe recessions or currency problems in home markets; and so on. Economically, moreover, this type of “predatory” behavior is rarely—if ever—effective in killing off competitors and establishing market dominance. (See this Don Boudreaux essay for more.)
Regardless, the U.S. government has itself acknowledged that “The antidumping rules are not intended as a remedy for predatory pricing practices of firms or as a remedy for any other private anticompetitive practices typically condemned by competition laws.” So that settles that.
So why, then, does the U.S. anti-dumping law even exist? As my former Cato colleague Dan Ikenson and others have explained, it was a simple political compromise: Developed countries—particularly the United States—agreed to lower their tariffs if they maintained the right to impose “trade remedies” restrictions on certain imports, i.e., anti-dumping duties and those targeting subsidies (“countervailing duties” or “CVDs”) and global import surges (temporary “safeguards”). In the United States, Ikenson details how this compromise was primarily about placating Congress during past free trade agreement negotiations, particularly at the World Trade Organization (WTO) and its predecessor the General Agreement on Tariffs and Trade (GATT):
